RE: Service Builder - read preference table

[Smilelws2010 lwz, geändert vor 10 Jahren.]

HI

Is it possible to read preference table for the portlet inside a method in the Liferay service builder, XxxServiceImpl.java?

If so how can we do that?

Thanks and looking forward to see the insights and possible solutions to read a name value pair from preference table in liferay.

You can create a method with ActionRequest or Renderrequest as a parameter in your xxxLocalServiceImpl.java class.

You can fetch the preferences by using
PortletPreferences prefs = request.getPreferences();

Now you can call this method from your controller class

Thanks Sanketh for the help.

But can you get ActionRequest or RenderRequest object inyour service builder implementation class? I doubt that.

Could you help me with that. And correct me if I am wrong.

Thanks

In your controller you can use:

xxxLocalServiceUtil.yourMethod(actionRequest);

and you can have a method in your xxxLocalServiceImpl

yourMethod(ActionRequest actionRequest){}

Thanks a lot Sanketh for the guidance.

I will try to do that and see how it goes.

Hello Smile,

With the following code snippet, you can get the preferences object in doView...

Portlet portlet = (Portlet)renderRequest.getAttribute(WebKeys.RENDER_PORTLET);
		PortletPreferences preferences = null;
		try{
			preferences =PortletPreferencesFactoryUtil.getPortletSetup(renderRequest, portlet.getPortletId());
		}catch(SystemException se){
			log.info(se.getMessage() + "occured in getting prefs");
		}

Yes Sanketh mentioned it correctly, you can always pass the actionRequest or renderRequest as a argument of *LocalServiceUtil and *ServiceUtil class.

For more details about custom configurations, see this link.

HTH.

Thanka and Regards,

Sorry, but this is really a bad idea...

SB code is meant to be used by multiple portlets. Each portlet has it's own portlet prefs (they are not shared nor overlap), so it's really a poor design to rely on the preferences of the calling portlet within your SB code...

Since the preferences belong to the SB code, you should handle them there. There's a number of different ways to accomplish this (a static singleton, spring injection, direct spring context access, etc.).

Thanks for the information David and Apoorva.

David,
I am not trying to read the preference of the calling portlet.

I am trying to read some values stored in the SB impl class based on the parameter passed by the calling portlet. And then I will have to look up the preferences table and get other details related to the parameter passed. Is that possible?

I will try to do the suggestions or will create a separate table other than preference and will try to query that using jdbc. Please suggest if this is going nowhere.

Reagrds,
